Computes the signal energy distribution in the time-frequency domain by using the short-time Fourier transform (STFT).
The short-time Fourier transform consists on obtaining the energy distribution on a section of a signal over time. This analysis is displayed on a joint time-frequency chart displaying the most energized frequencies over time.
LabVIEW 2012 (or compatible)
Steps to Implement or Execute Code 1. Open the "Moving STFT with Simulated Signal LV2012 - NIVerified.vi" 2. Select the Run button 3. Choose Select the Window and Sample lengths 4. Shift the sliders to see how the noise and frequency affects the displayed STFT chart.
